may be connected to this cross-head.. I rlhe details of construction necessary to connect 'this cross head `to' the engine shaft by a connecting rod,l are familiar to any one skilled in fthe art, the present invention resid ing particularly in the provision of the shollow Vpiston and the cylinder closed at the lower end, together .with the various valves and -otlier mechanism described. An annularbaille @ange lfthe wsllsvof which incline inwardly, is carried hy the yupper portionfof the hollow piston.` Packing rings 52 are also provided about said piston.

The operation of the ydevice is as follows: Upon the 11p-stroke oi the piston, a charge is drawn into the lower portion of the cylinder through the intake port 26, the valve 27 lifting to permit this charge to enter. Upon the down-strolgeot the piston this valve closes and the valves 47 lift to permit said charge to enter the interior oi the hollow piston. Alter the engine has.'

been given a revolution-or two by hand, Isucient oi the explosive mixture will have accumulated in the hollow piston to lift 'thenvalve 4() upon the down-stroke ol the piston. flhe explosive charge then passes yil'r'tO the upper portion oithe cylinder, where upon the upstroke of the piston it is compressed and tired in the After the engine starts to lire, the up stroke oi the piston draws the explosive .mixture in the lower portion o1 the cylinder. Upon the downstroke of the piston the explosive mixture Aenters the hollow piston and is compressed in said hollow piston until the piston in its downward movement uncovers thefexhaust ports V11, this relieves the .pressure upon the valve 40 and vpermits said valve I.to lift. Simulta neously with "the lliting.l of said valve, fthe .exhaust valve T15 opened. The upward rush oi ythe incoming charge -drives Athe .burned gases 4through the exhaust port vl2 and pipe 1 /1 to theenhaust 9. The valve l5 is, however, permitted 'to remain open but a very short time, said valve closing before the .incoming charge reaches it. Since the'dellector flange 51 directs said charge to the center of thecylinder, it follows that the burned gases will be driven down the Walls'ofthe cylinder and out of the exhaust ports 11. Upon the upward movement of the piston, the explosive mixture which is thus passed into the upper'portion of the Icylinder is compressed and fired and this operation .is-continued indelinitely.

lt will be eeen that the present invention provides means for automatically increasing the pressure ,in the hollow piston es the speed 4of the .engine increases. When an engineoifthis characterlis running at a very .high rate of speed, it willfoi vcourse 1loe understood that li the pressure-of the mixture -withi'nzthe hollow pis- I ton is not uullioientlggeat llores a fresh charge into eoliens a slow rate of speed, ten pounds of pressure will exist within the 'hollow piston, which pressure passes Ainto the 'upper portion of the cylinder when the valve 40 lifts, if, now the speed oi the engine should increase to such an extent that with ten .pounds ol 'pressure .in the hollow piston fthe charge cannot pass quickly enough intofthe upper portion of .the '.cylinder, it .follows vthat some of saidc'hnrge willbeleftinthehollowpiston. Il',

lfor instance at the heginningof the 11p-stroke ofthe piston only a portion of :the charge has had time to pass into the upper portion of the cylinder and two pounds pressure are left inthe hollow piston, this two pounds pressure will 'be -conned in said hollow piston, said pressure holding the valve 47 closed, Upon the rrp-stroke ofthe `piston the usual amount oi explosive mixture will he drawn into the lower portion of the cyl` index. 'the down-stroke oi the piston'this explosive gnixture will be forced into the interior of the hollow piston and will be added to the two pounds pressure'which .remain in seid/piston from ,the preceding charge, lrefusing the `pressure in said piston to ytwelve pounds. This action -will continue until the pressure in the piston is sufficient to force -a full charge oi explosive -mixture into the upper portion of the cylinder, no matter what the speed of the engine may be. By compressing the charge inthe lower portion of the cylinder and storing it inthe piston instead of foompressing it in "the crank case, I am enabled to compress said charge lin a-eorn'paratively small space and consequently am enabled fto secure a high degree of compression ivhen'theengine is 4running at a high speed.

1t is apparent that an operative structure would `-he provided -even though the valves 47 were omitted, for

the charge would then v.be compressed vagainst the head 25 until the Aexhaust ports l1 were opened, when the charge would begin to pass to the upper portionioi the cylinder.

1t isbo be understood that the present -invention is applicable to gas, gasolene, alcohol, or other explosive engines, but While the elements herein shown and Adescribed are well adapted toserve the Apurpose iorwhich they are intended, it is to be understood thatmy .invention isinot limited to the Iprecise construction set forth, but `includes within its purview such changes as vmay be made Within the scope of the appended claims.
